menu "Clock" config CLK bool "Enable clock driver support" depends on DM help This allows drivers to be provided for clock generators, including oscillators and PLLs. Devices can use a common clock API to request a particular clock rate and check on available clocks. Clocks can feed into other clocks in a tree structure, with multiplexers to choose the source for each clock. config SPL_CLK bool "Enable clock support in SPL" depends on CLK && SPL_DM help The clock subsystem adds a small amount of overhead to the image. If this is acceptable and you have a need to use clock drivers in SPL, enable this option. It might provide a cleaner interface to setting up clocks within SPL, and allows the same drivers to be used as U-Boot proper. config TPL_CLK bool "Enable clock support in TPL" depends on CLK && TPL_DM help The clock subsystem adds a small amount of overhead to the image. If this is acceptable and you have a need to use clock drivers in SPL, enable this option. It might provide a cleaner interface to setting up clocks within TPL, and allows the same drivers to be used as U-Boot proper. config CLK_BCM6345 bool "Clock controller driver for BCM6345" depends on CLK && ARCH_BMIPS default y help This clock driver adds support for enabling and disabling peripheral clocks on BCM6345 SoCs. HW has no rate changing capabilities. config CLK_BOSTON def_bool y if TARGET_BOSTON depends on CLK select REGMAP select SYSCON help Enable this to support the clocks config CLK_ZYNQ bool "Enable clock driver support for Zynq" depends on CLK && ARCH_ZYNQ default y help This clock driver adds support for clock realted settings for Zynq platform. config CLK_ZYNQMP bool "Enable clock driver support for ZynqMP" depends on ARCH_ZYNQMP help This clock driver adds support for clock realted settings for ZynqMP platform. source "drivers/clk/tegra/Kconfig" source "drivers/clk/uniphier/Kconfig" source "drivers/clk/exynos/Kconfig" source "drivers/clk/at91/Kconfig" source "drivers/clk/renesas/Kconfig" endmenu
